Question about Outlook Express

I recently converted from a PC to a Mac at work, and I want to ask about a calendar view.
On my PC, I could choose whether or not to overlay multiple calendars  or view several calendars (i.e. others on staff) side-by-side, which is my preference or else everything is cluttered and it's hard to distinguish what events belong to which calendar owner..

On my new Mac, I have found that the overlay view is the default and I can't figure out how to change the view so that these calendars are viewed side-by-side.
